Hmm ... I think this only happens with all things Sony. Lost my Clie disc before too. After that esipode I started to make a backup copy of all software discs I had and store them in separate locations. Anyway,

I'm made a copy of the disc and uploaded it to rapidshare. You can download the disc here.

No worries mate. Glad to help out. I recently just got my Librié and since then I use it everyday to read RSS feeds, my local newspaper, and some books I had wanted to read again. So I can understand how someone might feel if it suddenly didn't work. E-Ink is great eh?
